KT syndrome is a congenital disorder, i.e., it is secondary to the disease from the time of birth, and the best time to treat KT syndrome is when the patient is mature, at puberty, after the age of 12, when the lower limbs are basically developed and the muscles are well developed. Of course, it can be seen clinically that many patients are forced to undergo treatment before the age of 12 years old as a result of pain that becomes apparent after activity, or severe limitations in walking. KT syndrome is a congenital venous malformation that results in a rich blood supply to the limb, causing rapid limb growth, and premature treatment can lead to limb muscle hypoplasia, which can affect the patient’s future functional exercise and limb movement in the future. The process of excision may affect the functional exercise of the patient and affect the future movement of the limb.
